Abstract
The purpose of this paper is to investigate using a numerical simulation (computational fluid dynamics or CFD) the effect of the air supply location on the design and performance of the displacement ventilation (DV) system. The results are reported in terms of thermal comfort and indoor air quality. The study focuses on a typical enclosure in CBIT under local thermal and boundary conditions. This includes several pollutants typically found such as carbon-dioxide and volatile organic compounds (VOCs) were inv ....etc

Strength based and Displacement Based Design method for steel


Abstract

The performance based seismic design of Steel moment resisting frame structures aimed at controlling the structural damage based on precise estimations of proper response parameters. The primary focus of this study is on the development of a detailed assessment of the inelastic seismic behavior, response, and performance of typical ductile Steel moment resisting frame structures. This research tries to assess the Strength based and Disp ....etc

NDT TESTS ON CONCRETE

Rebound Tests
The rebound hammer is a surface hardness tester for which an empirical
correlation has been established between strength and rebound number.
The only known instrument to make use of the rebound principle for
concrete testing is the Schmidt hammer, which weighs about 4 lb (1.8 kg)
and is suitable for both laboratory and field work. It consists of a springcontrolled
hammer mass that slides on a plunger within a tubular housing.
The hammer is forced against the surface of the concrete by ....etc

SEISMIC ANALYSIS OF BRIDGES USING DISPLACEMENT-BASED APPROACH

By Chung C. Fu and Hamed AlAyed, University of Maryland

ABSTRACT
Nonlinear Static (Pushover) Procedure is specified in the guidelines for seismic rehabilitation of buildings presented by FEMA-273 (1997) as an analytical procedure that can be used in systematic rehabilitation of structures. However, those guidelines were presented to apply the Displacement Coefficient Method, which implements the well-known equal displacement rule with some modifications to est ....etc

This article describes the effect of tower displacement of two parallel transmission lines on the magnetic field distribution. Here, two parallel lines with the same working voltage and having the same span and in which the use of artificial tower displacement is made is modeled.Parallel transmission lines with different span lengths and different voltages produce tower displacements naturally and this is also modeled. Additionally, the effects like the spacing between the parallel lines, phase conductors arrangements and the transmission line ....etc

Abstract:
This seminar is intended to evaluate the applicability of Nonlinear Static Procedure by implementing the Displacement Coefficient Method to bridges. For comparison purposes, the Nonlinear Dynamic Procedure (or nonlinear time-history analysis), which is considered to be the most accurate and reliable method of nonlinear seismic analysis, is also performed. A three-span bridge of 97.5 meters (320 ft) in total length was analyzed using both the Nonlinear Static Procedure/Displacement Coefficient Method and nonlinear time-history. Nine ....etc
